TECHNICAL SOLUTIONS FOR ECOLOGICALLY SAFE AND SUSTAINABLE DEVELOPMENT OF SHELF DEPOSITS

Complicated environmental and climate conditions (ice conditions, temperature, wind direction) which is typical for the most Arctic shelf deposits, limit access to reservoir during the whole year. This reason determines necessity of searching alternative technical facilities for shelf deposits. Subsea turbo compressor units (STU) provide ability for whole-year reservoir production, and it sustainable development. The paper analyzes STU operation experience and shows advantages of it utilization, the main of which is ecological safety, low capital and operating costs, energy efficiency and other. Operating subsea compressor units, it components and types are described. Besides, the paper highlights the main problems of traditional electromechanical systems with compressor units for shelf deposits. For providing successful and effective Arctic projects it need to take into account not only exploitation experience of top-leader country and companies, but law and organizational systems for it providing. Paper shows the example of successful system on the base of effective Norwegian experience.
